This is an anion gap (21) metabolic acidosis in a patient who takes metformin with an acute kidney injury and elevated lactate. (diabetestalk.net)
Her initial admission laboratory results showed a blood glucose of 183 mg/dL, acidosis with an anion gap of 23, pH 7.11, β -hydroxybutyric acid ( β -HA) 9.6 mmol/L (normal 0.02-0.27 mmol/L), and lactate 0.65 mmol/L (normal 0.3-1.5 mmol/L).

What are the mechanisms of lactate metabolism and lactic acidosis? (ebmedicine.net)
Lactate levels add 1:1 to the acidosis reflected in the base excess. (pivares.com)

Experimentally, it has been found that patients with diarrhoea severe enough to cause hyperchloraemic acidosis have a negative UAG (average value -27 +/- 10 mmol/l) and patients with acidosis due to altered urinary acidification had a positive UAG. (anaesthesiamcq.com)

A normal anion gap metabolic acidosis is caused by the loss of bicarbonate with a reciprocal increase in chloride concentration. (medicoapps.org)
It typically arises from bicarbonate ion loss due to renal or gastrointestinal issues, such as diarrhea, renal tubular acidosis, or certain kidney diseases. (medical-definitions.net)
With metabolic acidosis, "acidosis" refers to a process that lowers blood pH below 7.35, and "metabolic" refers to the fact that it's a problem caused by a decrease in the bicarbonate HCO3− concentration in the blood. (msdmanuals.com)
Now, not all of the ions are easy or convenient to measure, so typically the dominant cation, sodium Na+, which is typically around 137 mEq/L and the two dominant anions, chloride Cl−, which is about 104 mEq/L, and bicarbonate HCO3−, which is around 24 mEq/L, are measured. (msdmanuals.com)
So, basically, metabolic acidosis arises either from the buildup of acid in our blood, which could be because it's produced or ingested in increased amounts, or because the body can't get rid of it, or from excessive bicarbonate HCO3− loss from the kidneys or gastrointestinal tract. (msdmanuals.com)
The anion gap is the difference between primary measured cations (sodium Na + and potassium K + ) and the primary measured anions (chloride Cl - and bicarbonate HCO3 - ) in serum. (medscape.com)

A 3-step approach is used to assess the acid-base disorder: (1) establishment of a primary disturbance, (2) determination of the serum anion gap, and (3) evaluation of compensation. (medscape.com)
The normal value for the serum anion gap is 8-16 mEq/L. However, there are always unmeasurable anions, so an anion gap of less than 11 mEq/L using any of the equations listed in Description is considered normal. (medscape.com)
The following equation is used to calculate the serum anion gap. (medscape.com)

Analysis of m ilk powder from the tin currently in use was found to be excessively high in salt with a sodium content of 843mmol/l (normal content of standard formula 30mmol/l) and a chloride of 833mmol/l (normal 50mmol/l). (pediatriconcall.com)
It is NOT the absolute chloride value that causes acidosis but the difference between Na and Cl! (pivares.com)
The newer autoanalyzers measure a higher serum chloride concentration, which lowers the normal range of the anion gap to 3-9 mEq/L (previously 7-13 mEq/L). Because these machines are not yet universal, it is essential to interpret individual results in the context of the laboratory's reference range. (medscape.com)

More rarely, high anion gap metabolic acidosis may be caused by ingesting methanol or overdosing on aspirin. (diabetestalk.net)
However, the highest risk for methanol poisoning is by swallowing ABHSR products containing methanol. (cdc.gov)
The clinical effects of methanol and ethanol poisoning are similar (e.g., headache, blurred vision, nausea, vomiting, abdominal pain, loss of coordination, and decreased level of consciousness), but methanol poisoning may result in severe metabolic acidosis and blindness, and can be fatal if untreated. (cdc.gov)
Clinicians should be highly suspicious of methanol poisoning when a patient presents with a history of ABHSR ingestion, compatible signs and symptoms, and laboratory findings (e.g., elevated anion gap metabolic acidosis). (cdc.gov)

It has been found experimentally that the Urinary Anion Gap (UAG) provides a rough index of urinary ammonium excretion. (anaesthesiamcq.com)
If the acidosis is due to loss of base via the bowel then the kidneys can response appropriately by increasing ammonium excretion to cause a net loss of H + from the body. (anaesthesiamcq.com)
If the acidosis is due to loss of base via the kidney, then as the problem is with the kidney it is not able to increase ammonium excretion and the UAG will not be increased. (anaesthesiamcq.com)
When excretion of Cl - exceeds that of Na + and K + , the urinary net charge is negative, and the assumption is that a substantial concentration of ammonium is present in the urine, which would be the case in metabolic acidosis of nonrenal origin. (medscape.com)
Urinary anion gap is an indication of excretion of which of the following? (medicoapps.org)
In response to acidosis, daily urinary excretion of NH4Cl can be increased from 30 mEq to 200 mEq. (medicoapps.org)

When the body produces too much acid or when the kidneys do not remove enough acid from the body, metabolic acidosis ensues. (medicalsupernotes.com)
During metabolic acidosis, kidneys normally eliminate NH4+Cl- to enhance the removal of excess H+ion. (medicoapps.org)
10 mEq/L). A urine anion gap of more than 20 mEq/L is seen in metabolic acidosis when the kidneys are unable to excrete ammonia (such as in renal tubular acidosis). (medscape.com)

The anion gap can be increased due to relatively low levels of cations other than sodium and potassium (e.g. calcium or magnesium). (wikipedia.org)
When this condition is suggested because of hypokalemia and a normal AG metabolic acidosis, it may be confirmed by findings of low sodium concentration in the urine from volume contraction, positive test results for stool phenolphthalein, or high fecal magnesium levels. (medscape.com)
The limiting factor of urine anion gap equation is that it is valid only if the urine sodium level is less than 20mEq/L. (medscape.com)
